Sequence Stratigraphy of Quaternary Deposits of the Continental Margin of Crimea

The article presents the results of seismoacoustic studies of the Crimean shelf carried out in 2018–2024 by the researchers of the Shirshov Institute of Oceanology of the Russian Academy of Sciences, using seismoacoustic and acoustic profilers. The studies made it possible to detail the position of the shelf and slope morphoelements, clarify the seismostratigraphic reference of reflecting horizons, and perform a sequence stratigraphic analysis of the Pleistocene-Holocene part of the section of the continental margin of Crimea. As a result of the seismostratigraphic and sequence stratigraphic interpretation of seismoacoustic profiles carried out in 2018–2024 on the continental margin of Crimea in the interval corresponding to the Quaternary period, the transgressive-regressive cycles and the associated tracts of high and low sea level stands were identified. It was shown that regressive-transgressive processes had a significant impact on the conditions of sedimentation.
